Specioation ofLetters Patent. Patented Application filed Febrtay 4, 1910.` Serial ,No 542,064.

To all whom it may concern:

Be it known that I, 1 `ERD1NANDBKRBL av citizen of France, and resident of 27 Avenue dItalie, Paris, France, have invented Improvements in and Relating to Suction Apparatus, ofV which the following is a specilication.

The presentinvention concerns improvements in and relatin to suction apparatus conveying fluid, sem1-fluid, and solid substances and has for its object to convey and to disebargesubstances as aforesaid, for instance dust, sand, and the like, the convey ing of the said substancesv being effected in a very quick and simple manner.

The principle-of this apparatus is to transing lnidand thepressure into aliving force and to'make use of this force in order to suol( the substances tobe ejected and to nieposit them in a convenient place.

The different parts are more clearly de scribed in their .coperative' relation the' body of the specification and in the 4,claim-l In order that. -thisQ-inventioir may 'be clearlyV understood-reference isf made to the y accompanyingdrawing, in Which-f` Figure lshows the apparatus in sectional elevation, while Figisa vertical sectionl of the same `on line i/ y of- Fig 1.-

The apparatus consists'chiefly vofa nozzle A, the body B, the -hopper `and a reciproeating slide D.

The nozzleA is a pipe like ,c ionne'ction,V

' the bore Vof which is sha ed liketwo cones connecting at their apex Fig. The purpose of this is tovimpartito the molecules' a greater speed, first by theconipression in the l,

converging cone, secondly' by the expansion in the sinaller diverging corio. .The nozzle A is fastened tothe body B by means of screws a' or any other suitable means. The body B is preferably of the shape shown 1n F 1g. 1,

and is provided with a channel H, which .is vertical in itsupper portion and the'nislopes away obliqu'ely, all sharp. edges being 'avoided.

The ho per C is of metal'and is secured tol the be y B by means of bolts and nuts or other suitable means. A chamber is formed between the hopper' C and the body 'B for the reception 'of'the slideD. 'Thisslide consists of a Hat metal plate'of rectangular Across section, and carriesa spike K whrch serves to break up larfe masses of material accumulating at and so prevent them slide is 4recip'roeated by means of a rodA E ing). Connected to the-body, so'y that it forms the continuation ofthev channel H, is a pipe G leadingtothe spot where it is desired jto deposit the mate'11al'.-' 'The pipes F and'Gare secured toa' cap or4 plate L and this latte lissec'ured to the body B and the hopper Csby meansV of suitable screws. An

openin I is arrangeddrom the chamber of the sli e B to the' channel H so asto allow for the. passage 0fdust or other. bodies which might'otherwise collectinthe slide chamber.v

or, steam as' it emerges rom the-nozzle .The upper end of tliehopper C is recessed 'the pressure. `is created in the inner part'of the cone. 'Thuswhen the rod Eis Lctuat'ed, any matter or' 'substance situated vin the hopr peris drawn in partly by its ownWeight andz 4partly by the lowering of the pressure under or channeled, so thatif desiredv an annular-f7 ring could be placed 4ontopfofj the hopperto' increase the. holding capacity.

This apparatus is specially applicable 'for unloading, ships cargoes, when they .consist of sand and similar materiahthougli it will' be understood that the g apparatus can used for 'many other purposes, Such foi- Tin-4 stance as the cleaning of I'lues jnstearn gen-4 erator furnaces..
